Are there any angles x and y that satisfy sin(x+y)= sinx+siny? Use an example to explain your answer.
Determine an expression using trigonometric ratios of special angles that simplifies to an answer of sqrt3/2. Use three different angles.
x and y represent two angles in standard position. x has its terminal arm in the first quadrant and y has its terminal arm in the third quadrant. If cosx=5/13 and cosy = -5/13 then find the value of 2sinx+2siny+2cosx-2tanx+tany+2cosy
